Crossing the Chasm and onto the Main Street: TV White Spaces Technology Spreads its Wings across Singapore with New Commercial Pilots

The Singapore White Spaces Pilot Group (SWSPG) today announced its next wave of TV White Spaces (TVWS) commercial pilot deployments in Singapore with Gardens by the Bay, Sentosa Development Corporation, the Housing and Development Board (HDB) and the Eurokars Group. Together with the first series of pilots announced in September 2012, SWSPG has created a strong case for transforming TVWS –unused TV broadcast frequency bands – into premium wireless connectivity channels in Singapore for both broadband and machine-to-machine (M2M) communications.

These announcements were made in line with the inaugural Global Summit on Dynamic Spectrum Access and TV White Spaces, organized by SWSPG and held at the Singapore Island Country Club.

From powering the data needs of mobile workers to enabling M2M communications in a smart city, wireless connectivity can indeed underpin the socio-economic progress of nations today. However, the exponential growth of wireless data traffic has created a strain on communications infrastructures in a world where spectrum resources are finite. Rising to this challenge, governments, policy makers, researchers and industry players are partnering to innovate on both agile spectrum management policies and more efficient spectrum utilization technologies. The set of SWSPG pilot projects are by far the most comprehensive TVWS commercial pilot efforts in Asia Pacific region. They are primary examples of public-private-partnership in adding value to economy and society through a combination of technology and policy innovation.

In recent years, TVWS has leapt onto the centre stage, with both spectrum policy and technological innovation. With supporting regulation, TVWS technologies turn unused TV broadcast frequency bands into complementary and cost-effective wireless broadband delivery channels and offer a new option for M2M data transmission. This is achieved through a set of highly desirable attributes associated with TVWS, including the ability to travel over longer distances and penetrate more obstacles such as trees, hills and buildings than technologies using higher frequencies, such as conventional Wi-Fi.

TVWS can enable greater wireless coverage in areas that were previously not possible due to challenging terrain and can improve business cases for organizations and network service providers through reduced total cost of ownership. The Singapore Island Country Club (SICC) successfully deployed a TVWS network that provides Wi-Fi coverage over its sprawling property covering multiple golf courses and several buildings. The TVWS deployment has delivered wireless connectivity where other technologies had previously failed, allowing for enhanced services for the Club members. The technology was simple and cost effective to deploy. In addition, the TVWS network allows the Club to trial new innovative resource management systems which have the potential of achieving 45% savings on external lighting costs, with SMART lights and the world’s first TVWS chip.

“The benefits of using TVWS technology are tremendous, be it to support ‘smart city’ infrastructure, to extend connectivity into previously challenging environments or to enable ubiquitous, reliable wireless connectivity that will enhance our lives. Alongside the commercial pilots, it is essential for the SWSPG and others to look at how this innovative technology really can make a difference in delivering a smarter, greener and safer environment for us all, the applications are only as big as our imaginations,” said Ms Tracy Hopkins, Corporate Vice President, Neul.

The new commercial pilots announced today by SWSPG are conducted under a test licence from the Infocomm Development Authority of Singapore (IDA) and utilize a TVWS Geo-location Database developed specifically for Singapore by Microsoft, with advice and inputs from IDA. These new pilots include:

  • Gardens by the Bay: Singapore’s iconic attraction has undertaken a TVWS trial to provide Wi-Fi connectivity to its visitors in a reliable and cost-efficient manner, without intrusive equipment and wiring built-ups over its greeneries. TVWS-based wireless connectivity was deployed to taking advantage of better propagation characteristics of TVWS signal. Currently three different sites at Gardens by the Bay – Supertree Grove, Meadow and Canopy - offer TVWS based Wi-Fi connectivity to visitors.
  • Sentosa: Singapore’s premier island resort getaway is implementing a trial to provide Wi-Fi coverage and deploy security surveillance cameras at Siloso Beach, Belawang Beach and the Merlion complex, while demonstrating the co-existence of multi TVWS vendors in a single environment.
  • Housing & Development Board (HDB): This pilot project responds to a need for video surveillance for rooftop security, car park enforcement and getting real time video from the lift system in HDB buildings. TVWS technology is expected to add efficacy in getting real time coverage, which would result in enhanced security and safety for the residence. Currently, all surveillance is done using cameras with local storage and manpower is required to collect them when needed. With the use of real time video recordings, it is possible to perform real time video analytics and allow multiple departments to share the same surveillance resources.
  • Eurokars Group: Singapore’s flagship car dealership will use TVWS to cost effectively extend their IT network to a number of outlying buildings. This will be complemented with unique concierge services: test-drive vehicle tracking, customer scheduled service management and other customer value added services.

Dr Tan Geok Leng, Executive Director, Institute for Infocomm Research (I²R) and Science and Engineering Research Council, A*STAR, said: “I am proud to say that Singapore is one of the pioneers in TVWS research, and continues to be a trailblazer in the TVWS movement globally. The successful pilots that we have seen in Singapore have set benchmarks in showcasing the potential of TVWS technology in delivering reliable and cost-efficient wireless broadband for multiple of commercial applications. With the new pilot projects, we hope to see TVWS being deployed in many other new and innovative applications.”

SWSPG was founded in April 2012 to develop pilot projects, collaborate on R&D efforts and support Singapore’s plan to implement a regulatory framework for adopting TVWS. Its founding members included I²R, Microsoft, StarHub and Neul and early members included Adaptrum, Power Automation, Singapore Island Country Club, Spectrum Bridge and ZDW Systems.
